✦ Synopsis

Compounds with Lateral Long-chaio Substituentsa New Molecule Structure Concept ' for Thermotropic Liquid Crystals

The molecules of thermotropic liquid crystals') have to be essentially rod-like; only relatively small lateral substifuents are possible. This general rulealready established by VOR-LANDERoften was proved and always confirmed (DEMUS et al. 1974; GUY 1962 GUY ,1975)).

The 1,4-bis-[~substituted-benzoyloxy]-2-substituted-be~es I are a substance class in which the role of lateral substituents R2 already was investigated in detail. There are
